RAZOR BLADE MAGAZINES Filed March 22 1951 2 Sheets$he6t l Sept. 27, 1955J. M. AUSTIN RAZOR BLADE MAGAZINES Filed March 22, 1951 2 Sheets-Sheet 2This invention relates to improvements in razor blade 15 changers andmagazines.

In my application Serial No. 159,038, filed April 29, 1950 (nowabandoned), I disclose a razor blade changer utilizing a magazineadaptable for receiving used blades when exhausted. The presentinvention is an improvement thereon, utilizing a blade pusher movingdiagonally and a diagonal slot in the magazine accommodating the same.

A mechanism and magazine embodying the invention in a preferred formwill now be described with reference to the accompanying drawing and thefeatures forming the invention will then be pointed out in the appendedclaims.

Figure 11 is an exploded perspective showing the method of assembly ofthe magazine.

The blade changer comprises a box having a body 1 and hinged cover 2.The box is provided with a clip arrangement 3 for holding a razor asindicated in phantom outline at 4, with the clip arrangement 5 forholding a spare magazine 6 and with a blade changer assembly designatedgenerally by the numeral 7.

In Figures 1 and 6, the razor 10 is shown in full lines in position fora blade change. As in my application above mentioned, means is providedfor holding the razor and a pair of magazines in a definite position sothat the blade change may be accomplished by operating the blade ejectorwithout need for positioning the razor and magazines with relation toeach other by the hands. The razor is of the hoe type, and has a backmember 11 carried by a handle 12 and terminating in an angle 13, formingthe upper member or cap for holding the blade 14 in position. A guard 15supports the lower surface of the blade and has a flange 16 lying fiaton the member 11 and pressed thereagainst by a spring 17. Lugs 18 on theguard pass through apertures in the back for positioning the guard withreference to the bac and further lugs pass through apertures in the backand extend beyond the surface of the back for use in opening the razorfor blade insertion as later described.

United States Patent 0 The blade changer assembly 7 includes a pair ofhooks 22, under which the cap portion 13 of the-back 11 is placed, asindicated in Figure 6, the elements 22 having angular extensions 23 forholding the cap in position when 5 so placed. The blade changer assemblyalso includes a clip 24 adapted to pass through an aperture 25 in theback. This clip has sufiicient spring to permit insertion of the razorasindicated in Figure 6, and to hold it in the position of Figure 6 whenonce inserted.

The used and new blade magazines are identical in construction, themagazine shown to the right of the various figures being the new blademagazine and the magazine to the left being the used blade magazine. Themagazine has a straight extension 31 at one end and an offset extension32 at the other. Extension 32 is generally parallel to the magazine wallfrom which it projects but is offset by substantially the thickness ofplate 7 adjacent aperture 33. The new blade magazine is held in positionas best shown in Figure 3 by extension 32 0 passing through an aperture33 in plate 7, so as to come under the plate for holding the magazinedown against it. A spring catch 34 is provided for holding extension 31at the opposite end of the magazine and the magazine is held in positionsidewise by a pair of projections 35. An

25 additional spring element 36 may be provided for cooperating with thecatch 34 and urging the magazine firmly into position against a frontstop 37. The holding means for the used blade magazine may be the sameas the means provided for the new blade magazine. The

39 various elements shown in Figures 1, 2 and 3 for holding the usedblade magazine are identified by the same numerals as used with theelements holding the new blade magazine with the addition of a primesufiix and require no further description.

The magazine may be conveniently formed by stamping and bendingoperations out of a single piece of sheet metal, as more fully describedbelow. The side shown in Figure 7 will be referred to, for convenienceof reference, as the top, while the side shown in Figure 8 will be 40referred to as the bottom.

The top of the magazine is formed with a full length slot between theedges of the bent over portions 40 of the blank of Figure 10. This slotcooperates with the blade changer pusher as more fully described below.The

stack of blades is held against the top walls 40 by a spring 43 so as toposition the top blade up against the walls or flanges 40 for ejectionby the pusher and insertion into a razor. The ejector or pushercomprises an element 44 pivotally and slidably mounted on a bar 45 held0 in end brackets 46 on the plate 7, and having an ejector tongue 48adapted to slide back and forth in the slot of the magazine for ejectingthe blades therefrom. The bar 45 carrying the ejector is slanteddownwardly with reference to the plane of the plate 7, so that as theejector moves pushing a blade out of the magazine and into the razor,the ejector follows the path of the slot between the upper wall flanges40 and urges the blade downwardly as well as outwardly from themagazine. When the blades are exhausted, a new blade magazine isinserted in the used blade position for receiving the used blades asejected from the razor, and the bottom wall 52 of the magazine is spacedfrom and overhangs end wall 41 to form a slot for receiving the usedblades. Rearwardly of this slot, the back wall 52 is struck down to forma deflector 6 bump or projection 53 for purposes described in detail inmy above mentioned application. The blade magazine conforms closely tothe profile of the blades and a notch 38 may be provided in an end wallto permit the ejector tongue 48 to be positioned in back of the topblade of the stack for ejecting it.

The blade changing operation is the same as described in my abovementioned application. The blade changing Patented Sept. 27,1955
